What is the difference between Digital and Lithographic Printing ?
Digital Printing:
The image is lasered directly onto a photo-sensitive drum and transferred
electrostatically to the image blanket. This is a toner-based process.
The image has a fine layer of oil applied to the surface, which is baked
on via a fuser roller.
Lithographic Printing:
The image is transferred via film separations to a printing plate and
then offset to a rubber print blanket. This transfers the image to the
paper.
Lithographic printing is a planographic process, which
means that the image and non-image areas are on the same surface. Oil-based
ink and water are applied to the plate. The ink will only adhere to the
image - as the water is applied to non-image areas the principal that
oil and water do not mix.
